A coalition of rivals charged on Friday that Microsoft Corp.’s new Vista operating system coming out next week will perpetuate practices found illegal in the European Union nearly three years ago.The group, which includes IBM, Nokia , Sun Microsystems, Adobe, Oracle and Red Hat, said its complaints made last year are yet to be addressed just days before Vista is due for release.

The European Commission found in 2004 that Microsoft used its dominance to muscle out RealNetworks and other makers of audio and video streaming software and that it made its desktop Windows deliberately incompatible with rivals’ server software.

“Microsoft has clearly chosen to ignore the fundamental principles of the Commission’s March 2004 decision,” said Simon Awde, chairman of the European Committee for Interoperable Systems (ECIS).

Microsoft said it had no comment. The Commission was not ready to act.

“We are in the process of examining this complaint,” a Commission spokesman said. ECIS disclosed on Friday that the latest additions to its complaint were made only last month, after it studied Vista.

Microsoft’s new Vista operating system is due for formal release on Tuesday, including a major rollout in Brussels, complete with a news conference and party.

“Vista is the first step of Microsoft’s strategy to extend its market dominance to the Internet,” the ECIS statement said.

It said Microsoft’s XAML markup language was “positioned to replace HTML,” the industry standard for publishing documents on the Internet. XAML would be dependent on Windows, and discriminatory against systems such as Linux, the group said.
